Abstract
A bearing, which has a first bearing ring, a second bearing ring, a rolling element interposed between the two bearing rings and a claw pole generator-type power generation unit. The bearing has a substantially space-neutral power generation unit which has a high filling factor for the induction coil. The first claw of the claw ring is connected to a magnetically conducting section of the body of the first bearing ring in a magnetically conducting fashion. The magnetic poles of the pole pairs are mounted so as to be connected to a magnetically conducting section of the body of the second bearing ring in a magnetically conducting fashion and the magnetic circuit is substantially closed via the two magnetic sections and the rolling element.
